A circle with a diameter of 4 mm has an area of : 12.57 mm2
24' 6"
If you mean 4 feet in diameter then the area is 4pi sqinches ie 4/2 x 4/2 x pi
If you mean a circle area than A = 63.61725 inch². Area A = pi times diameter² / 4.
No. The diameter of a circle (D) is twice the radius (r). Area = PI * r2 or PI*(D2/4)
The area of a circle with a diameter of 4 inches is: 12.57 square inches.
Area of a circle = (1/4) x (pi) x (square of the diameter)
The circumference of a 4 foot circle is: 12.57 feet(diameter x pi = circumference).
The area of a circle (in square hectometers) if the diameter is 4 cm is: 0.001257 hectometers2
Its diameter is about 4 cm rounded
A circle with a 4-foot diameter has a circumference of about 12.57 feet.
How many cubic yards in an 12 foot diameter circle with a 4 inch thickness?
pi * r squared is the formula; so 3.14 * 2 * 2 = 12.56
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
The area of a circle = (1/4 x pi) times (the diameter)2
A 4-inch diameter circle has an area of 12.566 square inches.
The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².
